Active parameter counts have plateaued while scale-up domains are set to expand 8x, signaling a shift from model size to interconnect as the frontier lever.
Frontier models have held active parameters per token near 280–288B since 2023, even as NVLink domain sizes jump from 72 GPUs today to 576 in 2027. For lab and app teams, this means the next wave of capability gains is more likely to come from larger coherent compute domains than from raw parameter scaling—and hardware roadmap decisions made now will determine who can exploit that shift.
Why this matters to you
If you're planning a 2027 training run, the rack scale-up domain (heading to 576) is your real ceiling — not peak FLOPS. The model you can train is bounded by what fits in one coherent NVLink domain.
The scissors
Frontier total parameters (left, log) against the NVLink scale-up domain (right) — the 8 → 72 → 576 staircase. Models got bigger because the coherent fast domain got bigger.

The Disclosure Cliff. 27 model releases in the corpus have no disclosed parameter count — the closed frontier stopped publishing in 2025. We track confirmed vs. inferred and flag the blanks honestly, because the blank is itself a finding.
